Yield Curve
Yield Curve, also known as 2s10s, 3m10y, inversion signals, is a Breadth, Sentiment & External Data concept. A reference entry: the Library explains it rather than implements it.
What is the yield curve?
The yield curve is the line traced by government bond yields across maturities, from short-term bills out to long bonds. For most traders it means US Treasury yields: 3-month, 2-year, 10-year, 30-year, and points between. In normal times it slopes upward, because investors demand extra yield for locking money up longer. When short yields sit above long yields, the curve is inverted, a shape with a long history as a macro warning.
Markets compress the curve into summary spreads. The 2s10s spread is the 10-year yield minus the 2-year; 3m10y is the 10-year minus the 3-month bill, and underpins the New York Fed's recession-probability model. A spread below zero means that segment of the curve is inverted.
The curve's shape reflects policy expectations, growth and inflation views, and term premium, making it regime information rather than an entry signal. Inversions have preceded US recessions in recent decades, but lead times have run from months to a couple of years, and equities have often kept rallying well after the first inversion.
Why there's no indicator for this
No study computed on a stock, index, or FX chart can produce the yield curve; the inputs are simply not there. The curve needs simultaneous yields across many maturities, sourced from Treasury market data such as the constant-maturity series carried on FRED. The price and volume of the symbol you trade contain no information about where the 3-month bill or the 10-year note is yielding.
A platform can chart the data directly: many feeds carry yield tickers and spread symbols, so 2s10s can be plotted as its own series. That is a data feed, not a derived indicator. Bond-ETF ratio proxies, such as long-duration versus short-duration funds, track slope direction tolerably well but cannot give the true spread level or the zero line defining inversion.
How to read the yield curve
The data is public; the skill is knowing which spreads matter.
- 1Pull constant-maturity Treasury yields from FRED or your feed, or chart spread symbols like 2s10s directly.
- 2Classify the shape: upward-sloping, flat, or inverted, noting which segment inverts.
- 3Track 2s10s and 3m10y against zero, watching the direction of travel as much as the level.
- 4Name the move: a bull steepener (short yields falling faster) usually reflects easing expectations, while a bear steepener (long yields rising faster) points to inflation or term-premium worry.
How traders use it
- As a recession and risk-regime flag: sustained inversion shifts the odds on a long horizon, and desks watch the eventual re-steepening just as closely.
- For sector tilts: curve slope drives bank-profitability narratives, often expressed through ratio charts of financials versus defensives.
- As one leg of intermarket analysis, read alongside the dollar through DXY correlation regimes and commodity trends.
- Cross-checked against equity internals: a curve warning carries more weight when advance/decline internals and new highs minus new lows are deteriorating.
- Directly, by macro traders running steepeners or flatteners in rate futures, weighed against positioning data such as COT analysis.
Yield curve vs related macro reads
Intermarket Analysis: Intermarket analysis is the broad framework linking bonds, stocks, commodities, and currencies; the yield curve is one of its highest-signal inputs.
DXY Correlation Regimes: Dollar regimes map currency strength onto risk assets; the curve is the rate structure behind those flows. Macro desks read them together.

Yield Curve FAQ
Does an inverted yield curve always mean a recession?
No. Inversions have preceded recent US recessions, but the sample is small, lead times vary from months to years, and an inversion can fade without a downturn. Treat it as a probability shift, not a schedule.
What is the difference between 2s10s and 3m10y?
2s10s embeds medium-term policy expectations; 3m10y, built on the 3-month bill, sits right on current policy. They can invert at different times.
Can I put the yield curve on my chart?
You can chart yield tickers and spread series where your feed carries them, and FRED publishes the data free. You cannot compute the curve from the price action of the symbol you trade.
Why do stocks often rally after the curve inverts?
The lag is long: equities have often kept climbing well after a first inversion, so traders pair the curve with faster gauges like the VIX and market internals for timing.
